Exterior Waterproofing

The exterior basement waterproofing process, explained

Exterior basement waterproofing helps keep your basement dry and your foundation structurally sound. The idea between exterior waterproofing is to seal water out and, at the same time, maintain the structural integrity of your home.

Waterproofing is important because excess water poses structural risks to your home and health risks to your family. Excess water leads to high humidity conditions which, in turn, leads towater-logged foundation walls, wood rot and structural failure. Plus, the presence of moisture inyour dark, damp basement creates an ideal breeding ground for mold growth, pest infestation and the spread of disease.

Look out for common signs of water damage: mold growth, sagging floors and foundation cracks. Once you notice any—or all—of these warning signs, call us immediately.

Exterior basement waterproofing products: Damp proof vs. water proof

Waterproofing is a bit of a misleading name—some of the best exterior foundation waterproofing systems are damp-proof rather than water-proof.

Not all of the best exterior foundation waterproofing systems are technically waterproof. See, there’s an important distinction between damp-proof and waterproof products.

Waterproof, by definition, means that a product that completely prevents water infiltration. Infact, many ”waterproofing products” control the flow of moisture through the substrate, but doesn’t stop it altogether. Damp proofing keeps the buildup of hydrostatic pressure and water leaks under control, but doesn’t necessarily keep all water out.

The minimal amount of water that makes it through your concrete wall will flow out through the ”weep holes”at the footing of your home or collected by your sump pump. And, to prevent excess water from reaching your foundation in the first place, it’s a good idea to have a comprehensive yard drainage system in place.

Although the specific details of a waterproofing project vary from home to home, this is the general process:

  1. We will excavate the dirt along your foundationWe will begin your exterior basement waterproofing project by digging up the dirt directly surrounding your foundation down to its footing. This will give us the necessary workspace to apply your waterproof or damp proof coating.
  2. Then we’ll clean your foundation and leave it to dryOnce your walls are uncovered, we will thoroughly clean your foundation walls to ensure there is a clean substrate for the coating application.
  3. Our technicians will apply the water- or damp-proof coating, membrane or sprayThere are many product choices for damp proofing. Many plastic products are often waterproof, as are rubber-based products. Asphalt sprays and coatings, however, are just damp proof. We’ll guide you toward the right product for your home’s particular waterproofing needs.
  4. We’ll install the Hydraway drainage system along the footing of your foundation wallLastly, we will install Hydraway’s drainage system—which never clogs—at the footing of your foundation.
